Platform / Modules / screenshot watermark

A screenshot you can prove. When, where, and from which session.

Every screenshot taken inside the application carries a cryptographically signed watermark — visible ID, hidden signed metadata. Survives compression and informal sharing. Verifiable end-to-end by support, dispute, and audit teams.

capture · transit · verify

From the screen, through WhatsApp, back to a verified record.

The watermark embeds at capture, survives the transforms of informal sharing, and resolves on the other side back to the signed context that produced it.

The watermark ID is embedded at the moment of capture, survives platform transforms in transit, and resolves on the verifier side back to a signed metadata bundle.
what the module gives you
  • embeds

    Cryptographically-signed metadata at capture

    Every screenshot taken inside the app carries a unique watermark ID linked to a signed snapshot — user, timestamp, app version, network state, device fingerprint.

  • survives

    Compression, resizing, platform transforms

    The watermark ID remains legible through WhatsApp, email, social platforms, PDF export. The signed metadata is recoverable from a transformed image.

  • verifies

    Cross-language libraries decode end-to-end

    JavaScript, Python, Java, .NET, Ruby. A support agent, dispute platform, or forensic investigator decodes the ID and retrieves the original signed context.

  • templates

    Custom logos, timestamps, compliance stamps

    Visible watermark layers are configurable per deployment — operator branding, regulatory stamps, jurisdiction marks. The signed payload underneath is invariant.

what teams do with it
  1. ·01

    Support tracing

    A user shares a screenshot of an error. The agent decodes the ID, retrieves the session context, and resolves without asking the user for reproduction steps.

  2. ·02

    Dispute evidence

    A merchant receives a customer screenshot of a confirmation page. The dispute platform verifies the watermark and confirms the screenshot was generated inside a legitimate session.

  3. ·03

    Incident forensics

    When a screenshot of confidential information surfaces externally, the watermark is the trail back to the device, time, and session that produced it.
